Hotel furniture in the custom industry using environmentally friendly paint
If be in metope lacquer industry, most consumer knows waterborne lacquer, but, in furniture industry, very few consumer knows however, why is this? Originally, waterborne lacquer goes up in the use of furniture, relevant standard is absent, cost is tall, construction is frequent wait for a problem, of course the most important is to lie in consumer to waterborne lacquer use do not like!
With the promulgation and implementation of increasingly strict national environmental protection laws and regulations, the requirements for painting are also getting higher and higher. Coating should not only ensure good anti-corrosion performance, high decorative performance, high construction performance, but also use good performance of materials and processes, reduce volatile organic compounds (VOC) emissions. In recent years, the water - based paint because of its relatively environmental components, become the main force of coatings. The biggest advantage of waterborne paint over solvent-based paint is that VOC emissions are greatly reduced. Compared with solvent - based paint, waterborne paint has the advantages of less environmental pollution, high leveling and good appearance. But the relative water - based paint construction requirements are high, good electrical conductivity, high corrosion defects. .

Waterborne paint construction technology:
1. Basic treatment: first remove the dust and oil on the surface of the wood, such as the surface of the wood stained with oil, can be used to clean the oil. Sandpaper is ground after dust and grease has been removed and the square wood of large sandpaper bags 5 stands on the ground. Ask for grinding, polishing and cleaning
2. Full blow transparent putty: putty to scrape, close, should not be scraped
3. Sandpaper: after the putty dries, use no. 1 sandpaper to smooth it, and then use the cloth to wipe it clean. With the same putty full scraping the second, and the requirements of the scraping head putty is the same, after scraping in the nail eye and the missing edge off the corner of the putty, wipe the full smooth after sandpaper, grinding smooth, to make clear wood grain, not to wear edges and corners, after grinding clean, with wet cloth wipe, dry.
4. Brush the first water-based varnish: when brushing to horizontal and vertical, thin and thick uniform, not flow not falling, brush lines smooth, do not leak brush, dry with 1 sandpaper polishing, wipe with wet cloth, dry. After every lacquer interval time is general summer about 6h, spring, autumn is about 24h, conditional time is a little bit longer better.
5. Spray color and repair color: spray color essence or color oil, have been painted over the head of the knot, nail eye and other places to repair color, according to the then color depth of flexible grasp, the color and the original color to be basically the same.
6. Brush the second water-based varnish: first check spray color and repair color, if meet the requirements can brush the second varnish, after the varnish dry, with 1 sandpaper polishing, wipe clean with a wet cloth, and then check in detail, such as there is a leak wipe putty and uneven, need to re-wipe the color putty, dry after local grinding, and wipe with a wet cloth.
7. Brush the third water-based varnish: after the second water-based varnish is dry, sand paper with 280 water, after grinding, wipe, the rest of the operation method as above.
8. Brush the fourth waterborne varnish: if you want to matte effect should add matte, after brushing the fourth waterborne varnish, to wait for the film dry solid hardening with 280-320 water sandpaper for polishing, polishing, grinding, grinding clean.
9. Polish wax: wrap polish wax in a clean white cloth, tie it tightly, rub it with your hands, rub it evenly, and wipe it until it is bright.
Quality requirements: no peeling, brush leakage, spot, brown eye scraping, clear wood grain, light and soft, smooth no block, feel good, no drop, wrinkle skin, color is the same, no brush marks.
Solution to burr:
After the wood is watered, the water penetrates along the wood fiber pipe and the micro gap in the wood grain, making it expand and expand, protruding the wood surface, and cannot be recovered after drying. So after wood besmear waterborne paint can appear wood grain protrusion, rise grain, give birth to burr to wait for a phenomenon.
1. Seal the wood surface with wax free insect gel paint
This method is better than water wet method, besides can prevent besmear waterborne paint to produce a grain, long burr outside, still can increase the layer sense of lumber. However, due to the color of shellac itself, the wood is often given a light amber tint. Insect glue paint back cover is very useful to old paint surface and the wood surface that may have been polluted by grease, demoulding agent, organic silicon compound, can prevent water borne paint to produce shrinkage cavity, fish-eye and other construction malpractice. In the process of coating, if found coating surface, especially old paint coating after shrinkage and fish-eye phenomenon, should be wiped off the paint has been coated with water, after polishing with dewaxing insect rubber paint back cover, and then coated with water paint. Insect glue paint is the alcohol solution of shellac, usable brush besmear or brush besmear construction method. After the back cover with more than 400# sandpaper polishing, and then use alcohol or wet cloth to clean the polishing surface, so as to increase the adhesion of the finish.
2. Wipe the coated surface with a wet cloth with extrudable water
Make the wood surface fully wet, after drying with fine sandpaper burr and particles formed. Then apply a primer and, when dry, gently polish with about 400# sandpaper. The porous wood should be coated with two primers before polishing, then the first primer should be diluted with 5% ~ 10% water.
Technical characteristics of spray room system
Waterborne paint spraying room construction environment has a great impact on the spraying quality, so the following conditions should be met:
(1) spray room brightness is bright and uniform;
(2) suitable temperature and humidity;
(3) no dust;
(4) good air supply system;
(5) good venturi slag removal system;
(6) complete fire protection equipment.
According to previous experience, to obtain good product quality, the following conditions should be met:
(1) illumination should be controlled at 750~1500lx;
(2) the best temperature is 22~26℃, and the best relative humidity is 55%~75%(65%).
(3) ash particle control requires that the value of 5 m is 1, and the value of 10 m is 0;
(4) the wind speed of manual section was 0.2~0.4m/s downward, and that of automatic section was 0.4~0.6m/s downward.
Other notes:
1. As the main component of water-based paint is water, the material used in the water-based paint circulation system must be stainless steel.
2. Water is highly conductive, so there is a big difference between the automatic spraying system used for spraying water-based paint and solvent based paint. In order to prevent the leakage of high-voltage static electricity to the main circulation pipeline, the water-borne paint robot USES a plunger pump instead of a gear pump to disconnect the paint circuit from the main circulation pipeline and prevent danger.
3. Winter construction indoor engineering should be carried out under the heating conditions, room temperature is kept balanced, should not be less than +10 degrees, and not sudden change, should set a person responsible for the temperature of the door and window, to facilitate ventilation and remove moisture, summer construction should be added in the paint white water, to prevent damp white. Water - based varnish construction to maintain ventilation. Prevent mildew in summer.
4. The general wood surface to be painted should be initially polished with 200# sandpaper and then polished with 600# sandpaper to make it smooth. Joinery pieces can be sanded directly with 600# sandpaper. Fine sandpaper grinding will make the grain close, reduce the grain grain phenomenon.
